Abstract

A custodial token platform may implement a single smart contract for outbound messages. The custodial token platform may deploy, to a blockchain distributed data store, a self-executing program that batches messages from the self-executing program to multiple addresses of the blockchain distributed data store that are external to a custodial token platform associated with the self-executing program. The custodial token platform may select, from the multiple withdrawal requests and based on selection criteria, a set of withdrawal requests to fulfill via a batch message from the self-executing program. The custodial token platform may broadcast, to the blockchain distributed data store, a message that calls the self-executing program. The message includes an indication of a set of external addresses associated with the set of withdrawal requests, and the message causes a transfer of a set of crypto tokens from the self-executing program to the external addresses via the batch message.

Description

FIELD OF TECHNOLOGY The present disclosure relates generally to token management, including techniques for self-executing program for outbound messages. BACKGROUND Blockchains and related technologies may be employed to support recordation of ownership of digital assets, such as cryptocurrencies, fungible tokens, non-fungible tokens (NFTs), and the like. Generally, peer-to-peer networks support transaction validation and recordation of transfer of such digital assets on blockchains. Various types of consensus mechanisms may be implemented by the peer-to-peer networks to confirm transactions and to add blocks of transactions to the blockchain networks. Example consensus mechanisms include the proof-of-work consensus mechanism implemented by the Bitcoin network and the proof-of-stake mechanism implemented by the Ethereum network. Some nodes of a blockchain network may be associated with a digital asset exchange, which may be accessed by users to trade digital assets or trade a fiat currency for a digital asset.

DETAILED DESCRIPTION A user may access a custodial token platform to purchase, sell, exchange, or trade digital assets, such as cryptocurrencies, crypto tokens, or the like. A custodial token platform may support various types of wallets for deposits, withdrawals, and storage. For example, the custodial token platform may generate inbound wallets associated with inbound addresses for user deposits of crypto tokens to accounts associated with the user. The custodial token platform may also use outbound wallets for supporting withdrawals of crypto tokens and cold storage wallets for security. In some cases, the custodial token platform may support a wallet orchestration procedure that moves the crypto tokens between the various wallets of the custodial token platform for various reasons including liquidity management and security. In some examples, the wallet orchestration may be performed manually by administrators of the custodial token platform or may be performed via a static configuration. However, as cryptocurrency markets are increasingly dynamic, wallet orchestration between various wallets of a custodial token platform is increasingly complex, and may require consideration of current market states, market histories, and current wallet balances. In some examples, a wallet orchestration procedure may periodically flush crypto tokens from inbound addresses to other addresses associated with the custodial token platform via flush transactions. For example, the flush transactions may transfer or flush crypto tokens from an inbound address to an outbound address of an outbound wallet to support user withdrawals via withdrawal transactions. The custodial token platform may transmit messages to cause withdrawals for each user and/or each withdrawal request. For example, withdrawal requests by three different recipients (e.g., three different outbound addresses) may result in three withdrawal transactions. A withdrawal transaction is associated with transaction fees and thus, multiple withdrawal transactions may result in significant transaction fees
